Ringtones and Notification issuesGeneral

I've looked all over the forums for an answer to this: I thought that I had found help on this somewhere before, but it must have been cleaned out or something, because several search terms have not turned it up.

I have a Droid Eris. I have Zedge. I have a certain notification sound that I downloaded from Zedge. It shows up on the list, but there is apparently no sound associated with the item in the list. I manually downloaded the notification to my phone to see if it would play on the phone at all...and yes, it does. But I can't select it from the music player to be a notification sound...all that lets you set is the main phone ringtone...and I don't want it for that.

I hooked up the phone to my PC and made sure all the files were in their correct and happy places...notifications in notifications folder, ringtones in ringtones folder, zedge in zedge.
